Answer:
26.9
Step-by-step explanation:
Right now we have '8' in the tenths place. That '6' following the '8' requires us to round up. Thus, 26.86 to the nearest tenth is 26.9.
Solve system of equation.
2x+y=10
-2x+2y=5
Answer:
(2.5,5)
Step-by-step explanation:
thats the answer
Answer:
The solution point is (2.5, 5)
Step-by-step explanation:
This is one of the very first steps you need to take in order to solve 2 equations with 2 unknowns. This does not require that you make any adjustments.
2x + y = 10
-2x +2y = 5 Just add. The xs cancel.
3y = 15 Divide by 3
3y/3 = 15/3
y = 5
=========
Now use one of the equations (the top one is easier) to solve for x
2x + y = 10 Substitute y = 5
2x + 5 = 10 Subtract 5
2x +5-5 = 10-5
2x = 5 Divide by 2
x = 2.5
The solution point is (2.5 , 5)

Answer:
1A: The area of a flat, or plane figure is the number of unit squares that can be contained within it. The unit square is usually some standard unit, like a square meter, a square foot, or a square inch.
1B: A radius of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length
1C: A diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle.
2A: A=wl
2B: A=πr to the power of 2
Step-by-step explanation:
1. Area = the measurement of the surface of a 2D shape.
Radius = a straight line from the center of a circle to its circumference.
Diameter = a straight line from one side of a circle to the other side, passing through the center point.
2. The area of a rectangle is found by multiplying the length by the width.
The area of a circle is found by multiplying the radius squared by PI.
3. Find the area of the paper and the area of the game pieces, then divide the area of the paper by the area of the game piece.

Jorge has $138.22 in his savings account. He deposits $10.75 every week and withdraws $31.68 every four weeks. What will his balance be in 8 weeks?
Answer:
Pretty sure the answer is $160.86
Step-by-step explanation:
you start off by multiplying 10.75 x 8 because that's how much he'll deposit at the end of an 8 week spand.
adding 86+138.22= 224.22
then you subtract 31.68 two times from that as he withdraws 2 times in the 8 weeks, giving you the answer of 160.86.
hope this helps xx have a good day :)

find the midpoint of the segment with the following endpoints (2,4) and(8,8)
Answer:
(5,6)
Step-by-step explanation:
just answered a similar question for you a while ago so I have updated by response to match the different values:
the midpoint formula is
(x1 + x2/2) , (y1 + y2/2) <-- both the x1 and y1 coordinates also are divided by 2
so to solve for the midpoint, we take our endpoints and plug it into the formula
we will list the coordinates as the following to plug it into the formula:
x coordinate 1 = 2
x coordinate 2 = 8
y coordinate 1 = 4
y coordinate 2 = 8
substituting these values into the formula we get this:
x =(2 + 8/2) , y = (4 + 8/2)
x = 2 + 8 = 10/2 = 5 which is our x coordinate for the midpoint
y = 4 + 8 = 12/2 = 6 which is our y coordinate for the midpoint
in an ordered pair it would be (5, 6)
Final answer:
The midpoint of the segment with the endpoints (2,4) and (8,8) is (5, 6).
Explanation:
The midpoint of a line segment is the point that is equidistant from both endpoints. To find the midpoint of a segment with endpoints (2,4) and (8,8), we can use the midpoint formula.
The midpoint formula is given by:
M = (x1 + x2)/2, (y1 + y2)/2
Using the given endpoints, we substitute the values into the formula:
M = (2 + 8)/2, (4 + 8)/2 = (10/2, 12/2) = (5, 6)
Therefore, the midpoint of the segment with the given endpoints is (5, 6).

Mairisa gets $8 per week for an allowance. She saves 25% of her allowance each week. How long will it take Mauritania to save $16. Question :#7
8 weeks
First, find how much money Maurisa saves each week. 25% is the same as 1/4, and 1/4 of 8 is 2, so Maurisa saves $2 each week.
Finally, just divide $16 by $2 per week to find that Maurisa will take 8 weeks to save $16.

Use the grouping method to factor the polynormial below completely. 10x^3 - 35x^2 + 6x - 21
The polynomial 10x^3 - 35x^2 + 6x - 21 is factored using the grouping method to obtain (2x - 7)(5x^2 + 3).
To factor the polynomial 10x^3 - 35x^2 + 6x - 21 using the grouping method, we first look for a common factor in each group separately and then factor out the common binomial factor.
Split the polynomial into two groups: (10x^3 - 35x^2) and (6x - 21).
Factor out the greatest common factor from each group: 5x^2(2x - 7) and 3(2x - 7).
Now we have 5x^2(2x - 7) + 3(2x - 7). Since both terms have a common binomial factor of (2x - 7), we can factor this out: (2x - 7)(5x^2 + 3).
So, the factored form of the polynomial 10x^3 - 35x^2 + 6x - 21 using the grouping method is (2x - 7)(5x^2 + 3).

1. A(x)= 5,000^(0.96x)
2. A(x)= 5,000(0.959)^x
3. A(x)= 5,000 + 0.04x
4. A(x)= 5,000^(1.04x)
5. A(x)= 5,000(1.041)^x
Answer:
Option 5. [tex]A(x)=\$5,000(1.041)^{x}[/tex]
Step-by-step explanation:
we know that
The compound interest formula is equal to
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
[tex]t=x\ years\\ P=\$5,000\\ r=0.04\\n=12[/tex]
substitute in the formula above
[tex]A=\$5,000(1+\frac{0.04}{12})^{12x}[/tex]
[tex]A=\$5,000(1.041)^{x}[/tex]

Suppose you can chose from 3 different shirts, 2 pairs of pants, and 5 pairs of shoes. Use the fundamental counting principle to find out how many different outfit combinations you can make.
Answer:
You can make 10 combinations.
Step-by-step explanation:
you can make 10 combinations because all you have to do is just add all the numbers then you get 10
We want to find the total number of combinations of outfits, given that we know the number of each type of clothes that you have.
Using basic counting, we will get that there are 30 different outfit combinations.
Let's see how to get that:
To count the total number of combinations, the first thing we need to find is the selections.
Here we have 3 selections:
Selection of shirtSelection of pantsSelection of shoes.Now we need to find the number of options for each one of these selections:
Selection of shirt (3 options)Selection of pants (2 options)Selection of shoes. (5 options)To get the total number of combinations, we just need to multiply all of these numbers of options, we will get:
3*2*5 = 30
This means that there are 30 different outfit combinations.

Write the standard equation for the circle center (-6,8) that passes through (0,0)
Answer:
D
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
here (h, k) = (- 6, - 8), thus
(x + 6)² + (y + 8)² = r²
The radius is the distance from the centre to a point on the circle
Calculate r using the distance formula
r = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 6, - 8) and (x₂, y₂ ) = (0, 0)
r = [tex]\sqrt{(0+6)^2+(0+8)^2}[/tex] = [tex]\sqrt{36+64}[/tex] = [tex]\sqrt{100}[/tex] = 10
Hence
(x + 6)² + (y + 8)² = 100 → D

Answer:
Correct choice is C) [tex]6x^3-22x^2+24x-8[/tex].
Step-by-step explanation:
Given that the dimensions of a box are x, 2x, and 3x.
Now each dimension is decreased by 2.
Then new dimensions of a box are (x-2), (2x-2), and (3x-2).
Now let's calculate the volume of the box which is given by
Volume = (Length) x (Width) x (Height)
[tex]=(x-2)(2x-2)(3x-2)[/tex]
[tex]=(2x^2-6x+4)(3x-2)[/tex]
